Finally, there's the global-cooling spell. The world hasn't been warming since 1998, and an article in the journal Nature says warming won't pick up again until 2015. Since global warming is a long-term trend, a decade-long or more stall in temperatures doesn't mean much -- except that environmentalists have banked so much politically on whipping up hysteria based on imminent catastrophe. The stall in temperatures shows how little we know about global warming.

No matter what the price of gas is, the most sensible policy in the U.S. is to avoid costly schemes to fight global warming. If our economy keeps growing, we will be better positioned -- richer, and more technologically proficient -- to help others mitigate its effects decades from now. Senate Majority Leader Harry Reid huffs that global warming is "the most critical issue of our time." Really? More critical than energy prices? Than health care? Than wages? Than terrorism? Than nuclear proliferation?
